Do you know of any organizations in construction, manufacturing or project management that are using Holacracy? I see many examples in consulting/professional services and software development but not many in more concrete fields.

I'm collecting evidence that Holacracy is a workable, and even exceptional operating tool for a clean tech start-up. The team is convinced already, but we need to prove our system to private equity investors. Therefore, examples of how it is working in similar industries would be ideal. 

Many thanks for any pointers or examples you can share. 

Cheers,

Angela
